Looking for open-world games with a "feel-good" setting—less dark and brooding

I've been thinking about how much I love Far Cry 3—not just for the open-world freedom but because the setting is so vibrant and the combat is just fun. It’s a refreshing break from all the dark, war-torn, and post-apocalyptic settings that so many games lean into.

I’m looking for recommendations on open-world games that have a more “feel-good” atmosphere—something colorful, adventurous, and fun to explore, without that constant sense of doom and gloom. A tropical or lively setting would be great, but I’m open to anything that gives off that energy.

Bonus points if:

The combat is fun and engaging

The world feels alive and enjoyable to explore

It doesn’t take itself too seriously

Any recommendations? I’d love to hear what games scratch that itch for you!
